My presentV inventionl relates toy an improvenienti in steel barges ofthe type set kforth in my copending patent application for steel barge construction, Serial No.

and collaborateswith the framing of ythey 15 barge, and whereby greater economy in the building of the same is accomplished, than by present methods.,

'The above noted economy is accomplished mainly by the fact that 'the present new go construction obviates the use of forgedcollars heretofore utilizedkto form framing between the channel flanges, `each of such collars 'having to be made and fittedseparately owing Y to ynon-uniformity ofy the channel spacing,such non-uniformity ordinarily requiring the making ofseparate templets for eachy channel collar after the hull structure is erected. This, obviously, is very expensive and my present l construction eliminates 30 this. e Y In ybarges of the present type it isrhighly desirable, so far as is possible, that standardV 1 structural shapes bef'utilized in the building thereoffwith a minimum number of special y35 pieces, on the ground of economy in the labor cost of manufacture, anda saving in thev cost ofmaterial entering into such structura. 'n Y n These and other capabilitieswill be ascertained as .the herein descriptOIl Proceeds,

and it is obvious Vthat. modic'ations thereof may be'made without departing from the spiritof the invention or .the-scope of the 45 appended claims. Y n

Inmy present 'construction all of the conn' ponent lparts of my present invention utilize', so far as is possible, standardstruc-l tural shapes for the construction of barges of this type, ysuch as is vsetforth-in United' States Patentsy Nos. 1,596,728Jand 1,647,155, issued to Ellis onv Aug. 17,1926, and Nov.. l, 1927, respectively,andasa continuation of this, Ihave utilized certain standard structuralKV irf'on shapes, ase will fbe herein-I 70 Y after fully disclosed, for'thefconstruction ofvv bulkheads within al vessel ofjthetype described.l" For instance, in Fig; '1,I the deck l iis shown as' being yconstructed of' channel sec-'5 75. tions orfbeams-2friveted"together at theirf flanges 3, and theopposite 'sides ofthe vessel are ysimilarlyconstructed, as indicated by similar indices thereon, as is alsol the .bot-f tom, generally .denoted bye.. f

The bilge portions 5 of the hull, as will be noted'by examination:l ofthe enlarged fragmentaryportion of F ig.,4, are also si1ni'` larly-constructed except that the channel? Y beams 2, as 'previously described,are bent 95. so thatfits flanges 3 are broughtat right: angles to; oneV another by bending the webi portionl 6, lVigll,y to conformi to `the kbilge bendy'as Shown.lr` Y I In the construction of my bulkhead Within'y 90 f the hull fof af vesself constructed of channel utilize, asis shown in Fig'. 2, angle'frames, 95"

generally denoted by 6these angles being preferably of kunequal legs, and as shownin Fig. 5 the shorter legs of these angles 'are slotted at channel-flange spaced intervals so kas to permit of the introduction of the im v Anjouter ybil flanges 3 along the length of the angle members 6, these slots 7 being extended into the longer leg 9 thereof, as indicated in the fragmentary view, Fig. 3. The short interrupted fiange 8 of the angle rests against and is riveted to the webs of the channel beams while the longer flange 9 projects angularly awsiiy therefrom, this being fully indicated in ig. 3.

After thefslotting and fitting of the angle frames 6 to the respective positions and channels 2, for locating the bulkhead plates, the short leg 8 of the angle is rivets 9', Fig. channel webs 2 by means of rivets 9', Fig. 3. The slotted openings 7 in frames 6, into which are introduced the upstanding flanges 3 of the channels, are then welded to the flanges 3 at their points of Contact, `as indicated by the dotted lines y1() in Fig. 3 so that the slotted bulkhead angle frames 6 are welded, at intervals, to the flanges' 3 of the channels 2 andby such welding the slotted jointures are made into an integral and `watertight construction.

After the frames k6 .have been placed in position, rivetedand welded, as abovev described-,the bulkhead plates 11 and 12 are then laced in position, they being overlap at their mid section as at 13, in some instances, and the outer edges 14 of the said plates are then `riveted to the long leg 9 of the angle frames 6 by means of rivets 15, this detail being fully shown in Fig. 3.

Thereafter, .for the 'purpose of stiffening the bulkhead plates against bulging in either direction, they are stiffened by the riveting thereto of a plurality of vertical standard angle bars 16, Figs. 1 and 2, these running substantially from the Vdeck framing to the bottom framing of the barge and thereby stii'ening the transverse bulkheady forming lates 11 against undue displacement..

. At the bilge portion B of the rhull structure, Figs. 1 and 4, it will be noted that the angle frame there noted is curved 4to fit the bent bilge vforming channel beams2, the said bilge `forming channels being affixedto their associate hull forming channels 2, as previously described.' The bilge forming angle frame piece, B is a separate piece of an le framing bent as previously described, an is thereafter riveted, "as by rivets 15, to thehulkhead plates v12, and is also Weldedto the Vflanges of the hull forming channels. e reinforcing platey 17, 'bent to conform to t eshapeof kthe web 6y of the bilgeV channel beam, yis affixed to the kbilge aociated channel beamsby rivets 18. Thus they bilge portion isreinforced at this point and cooperates with thel interior angle framingmembers 6 at the sides and bottom of the barge to encompass a rigid bilge con-y struction and at the same time acts as a corner anchorage yfor the bulkhead plates 12.

yIt will be noted from the foregoing that in the bulkhead construction there are only three structural elements used, namel the framing 6 which is notched and wel( ed to the longitudinal hull forming channel beams 2, the transverse bulkhead forming plates 11 and l2 and the bulkhead plate reinforcing angles 16. It will further be noted that owing to this construction that the bulkhead plates themselves are integrally aiiixed, throu h the angle frames 6 to the hull forming c annel beams in a rigid manner, by reason of the Welding and riveting, thereby transversely reinforcing the hull structure of the vessel, and that the bulkheads are in turn reinforced by the vertical angle braces 16 thereby creating, at intervals, throughout the longitudinal length of the barge proper, a series of transverse hull reinforcing watertight compartment forming `members which involvel aV very simple construction and admit of the practice of a greater economy in the construction of bulkheads, than heretofore accomplished by customary practice.
